Race your friends on the 70ft pinewood derby track or take to the air on our flight simulator. Discover the power of light, and make your own mini-laser show. There are also new open-ended exhibits that invite visitors to imagine, create, and construct various inventions from paper flying machines to structures from PVC pipe.

Science Park also features a variety of live shows and demonstrations that complement and enhance the topics in the exhibit. We’re always creating new exhibits for Science Park, so check our website articles for news.

Wondering why you always feel hotter when wearing black instead of a light color? Try this experiment to prove that there are valid reasons for this to occur. This experiment looks at different types of colors reacting to the sun and which one will generate and capture more heat. Check it out!

What You Will Need:

2 Identical Drinking Glasses or Jars

Water

Thermometer

2 Elastic Bands

White Paper

Black Paper

Instructions:

Wrap the white paper around one of the glasses using an elastic band or sellotape to hold it on.

Do the same with the black paper and the other glass

Fill the glass with the exact same amount of water

Leave the glasses out in the sun for a couple of hours before returning to measure the temperature of the water in each.

What is Happening?

Dark surfaces such as the black paper absorb more light and the heat than the lighter one such as the white paper. After measuring the temperatures of the water, the glass with the black paper around it should be hotter than the other. Lighter surfaces reflect more light, that’s why people with lighter colored clothes in the summer keep cooler.

Did you know that talking on a cell phone for a prolonged period might actually increase brain activity? Cell phones emit energy in the form of electromagnetic radiation and scientists are on a mission to figure out what effects this can have on the brain.

According to Science News, a recent experiment took place where 47 participants had two cell phones strapped against each ear. The phone on the left ear was turned off and the phone on the right ear played a 50-minute message, but was set to silent. Their goal was to study brain activity from the phone itself, not brain activity from listening and engaging in conversation. Scientist used a PET (positron emission tomography) Scan to study the brain activity. The test allows us to see what is going on inside of the body using injections of radioactive material to measure chemical reactions in the brain and creating three-dimensional pictures.

The results of the PET scan showed that the left side of the brain had no changes from the experiment. Conversely, the right side of the brain was using large amounts of glucose, almost as much as a person talking. Glucose is a sugar that provides fuel to the brain. These results allow scientists to conclude that brain cells are active even when the participants hearing nothing. The activity was most likely set-off by the radiation from the cell phone.

The experiment arose from the question “Are there any health risks involve with cell phone usage?” There is still considerable debate, but scientists who believe there are give a few suggestions to be on the safe side:

Do not talk for long periods of time with a cell phone pressed against your head.

The traditional laser has been turned inside out, producing what scientist like to call an “anti-laser”. This device is actually called a coherent perfect absorber and has the capabilities to absorb rather than release a stream of light.

In a traditional laser, energy is injected into a medium that is transferred between two mirrors while stimulating photons, which are then reflected back through the mirrors, resulting in an amplification of light. The anti-laser works in a similar fashion, except the medium contains an absorptions component instead of amplification one. Scientists believe the anti-laser has the potential to be used in fields such as computing and medical imaging; leading to instrumental advances in technology. This innovational physics device was discovered by scientist at Yale University and has been noted as a surprising and exciting achievement in the science community.

National Geographic’s Little Kids website has found a fun and messy experiment to teach your little kid about the liquid and solid phases of matter. Before conducting the experiment read over all the directions with your child and have them form a hypothesis, what they think will happen. Encourage their curiosity by having them feel all the components of the experiment, water and cornstarch, before making their hypothesis. Once they have decided on their hypothesis conduct the experiment.

Here’s what you’ll need for this cool experiment:

Newspapers (This can get very messy!)

Mixing Bowl

16 ounces of Cornstarch

Measuring Cups

Water

Blue Food Coloring (or whichever color your child prefers)

Experiment Procedures:

Pour the 16 ounces of cornstarch into the mixing bowl.

Use the measuring cups to add 1 ½ cups of water to the cornstarch.

Add about 15 drops of food coloring to the mix.

Here is the fun part! Use your hands to mix the experiment ingredients.

Now they you’ve made your blue goo ask your child some questions as they play with it. Was their hypothesis correct? Or was it incorrect? How does the blue goo feel? Does it feel more like the water or the cornstarch? Point out to your child that if you squeeze the blue goo in your hand it feels like a solid but if you open your hand it spreads out like a liquid. The blue goo can act as both a liquid and a solid!

If you thought invisible cloaks were just used by Harry Potter, think again. Two independent research teams have created carpet cloaks that allow you to experience an object vanishing. The researchers discovered this with the use of crystals, called a calcite prism. The crystals are placed in a precise location so that when the correct light hits the cloak and the crystals' “optical properties” kick in, the object you are viewing disappears before your eyes.

They are currently only able to make smaller objects disappear, such as an ant or piece rice. Scientist still have a lot of work ahead of them in advancing the invisible cloak, making it 3-D and making larger objects disappear, but they are on the right track. Where does the future lead? Instead of hiding objects, scientist would love to reveal them, a new kind of ABRACADABRA!
